Light's Criteria: Exudative Effusions will have at least one of the following:
<ul>
	<li>Pleural fluid protein / Serum protein &gt;0.5</li>
	<li>Pleural fluid LDH / Serum LDH &gt;0.6</li>
	<li>Pleural fluid LDH &gt; 2/3 * Serum LDH Upper Limit of Normal</li>
</ul>
Note: While Light's Criteria are reported to be highly sensitive for exudative effusions, their specificity for exudative effusions is only 83%.</div>
